EarthX Lithium Battery Experimental Aircraft 12V/12.4 AH Case E ETX680
MFR Model# ETX680
Overview
|
Note: Not FAA Approved. Intended for use in experimental aircraft only. When quality, performance, and safety matter, EarthX is the most trusted and used brand by experimental aircraft manufacturers and experimental aircraft owners, and endorsed by engine companies such as Rotax, Continental, ULS Power and Viking. Remove weight and increase power, all with one product! These ETX Hundred series (ETX680C, ETX680, ETX900 and the ETX1200) batteries are recommended for your primary engine aircraft battery. These models are equipped with redundant electronic circuits on the BMS board and have an LED battery fault light indicator to alert you to cell health and state of charge. The battery management features include over discharge protection, over charge protection, short circuit protection up 1000 amps, excessive cranking protection (temperature sensing) in addition to integrated cell balancing technology. With an EarthX lithium battery, you will gain a significant amount of cranking amps and drop a minimum of 11+ pounds instantly by switching from a lead acid battery. Please view the Aircraft Application Flowchart under the documents tab for assistance in selecting the correct EarthX battery for your application. Additional Specs

Features
- The ETX Hundred series is fully protected by an integrated Battery Management System that protects the cell’s from over discharge, over charge, short circuit, thermal protection and built in cell balancing to ensure charge levels are equal (balanced) 100% of the time for optimal performance
- and life.
- The most trusted and used lithium battery on the market. Multiple experimental aircraft manufacturers and experimental engine manufacturers such as Rotax Engines, Continental Motors, UL Power Engines and Viking Engines approve the EarthX brand.
- LiFePO4 chemistry, the most abuse tolerant of all lithium battery chemistries.
- Higher voltage while cranking mean faster starts.
- Extremely light weight, 70-80% lighter than your lead acid battery.
- 4,000 charge cycle life versus 350 charge cycle life of a lead acid battery. Can last up to 8 years.
- Environmentally friendly, no hazardous lead or acid, will not corrode or sulfate.
- Wider operational temperature range than a lead acid battery. (-22° F to 140° F, -30 ° C to 60° C) . A lead acid’s operational range is(-40° F to 113° F or -40° C to 45° C).
- Vibration tested to DD-311 FAA standard.
- Low self discharge rate and fast charging.
Specifications
- Volts: 13.2
- 1 Hr 1C Rate: 12.4
- Crank Amps (PCA/CCA): 680/320
- Weight: 4.1 Lbs
- Case Size L x W X H (In.): 6.5 x 3 x 6.6
Why Choose EarthX
- You will instantly remove 11+ pounds compared to the lead acid battery in your experimental aircraft! Now that is a huge weight savings.
- Significant increase in cranking power. If you have been using the PC680, you will increase your CCA’s from 170 to 320 and the PCA’s from 520 to 680! Now that’s power to crank your engine!
- Now you can easily have a backup battery and not worry about the additional weight. In fact, if you switch from a lead acid battery and add a backup battery, so you have a primary and a backup, you still have decreased your overall weight by 50%! Note that only the ETX680C/680/900/1200 have the aircraft specific BMS.
- Innovative and sophisticated BMS designed and engineered with redundancy for safety, reliability, and performance. These are EXCLUSIVE features!

I replaced an Odessey lead acid battery with the EarthX. I get far better CCA with the EarthX making cranking of my engine so much better. The EarthX is also 11 lb. lighter than the Odessey. Plus the EarthX recharges far faster.
